Save the TigersPPT,第二部分内容:合作探究 考点突破
考点1 the number of……的数量
*At the beginning of the 20th century, the number of tigers in the wild was around 100, 000.
在20世纪初期, 野生老虎的数量大约是十万。
*A number of students like playing computer games.
许多学生喜欢玩电脑游戏。
【妙辨异同】 the number of与a number of的辨析
(1)the number of是固定短语, 意为“……的数量”, 后接可数名词复数, 但中心词是number, 所以谓语动词要用单数。
(2)a number of为量词短语, 意为“许多; 大量”, 相当于a lot of或lots of, 中心词是该短语所修饰的可数名词复数, 所以作主语时, 谓语动词用复数形式。
【即学活用】
①-A number of volunteers______willing to teach in China’s rural areas.
—Yes, the number is getting______.
A. is; bigger and bigger
B. are; bigger and bigger
C. is; more and more
D. are more and more
【解析】选B。考查主谓一致和形容词比较级的用法。a number of. . . 作主语, 谓语动词使用复数形式, 排除A、C; 第二个空表示“数量在变得越来越多”, 故选B。
